Polymer plastic body worn case

ABSTRACT

The spread of wireless communication is growing. A handy holder provides an innovative cost-effective support for communication devices when controlling movements of people inside or outside of a building. The idea is to use a plastic case capable of repelling bacteria, a case with perpendicular walls adapted to support a small rectangular radio communication such as walkie-talkie radios. In preparing plastic walls, it is important to drill holes for the unobstructed passage of broadcast waves and to provide openings for communication ON/OFF. Perpendicular corners are obtained by carving a width of plastic until there remains a thin wall which may be folded either internally or externally, thereby creating a link to a flared normal direction.

The present invention is a Continuation in part of a prior application U.S. Ser. No. 12/319,758 filed on Jan. 13, 2009 for a body worn case for electronic devices such as two-way radio transceiver, commonly called walkie-talkie radios.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In the following description and in the accompanying drawings, the numeral numbers refer to identical parts in the various Figures.

In FIG. 1 a polymer case 20 is shown incomplete, in a partial view. There appears to be a front wall 22, a left wall 24 comprising a mike slot opening 25 for microphone attachments, a bottom wall 26, a right hand wall 30, a thickness 28, a wall mount piece 42 which appears to be partially removed, holes in the back wall to fix the left and right walls. The front wall has holes for a speaker and for sound waves 31 and a mike slot hole 33. The case bottom wall 26 has evacuation holes 32 for air and moisture. The bottom wall is covered by two bottom folds 36 held in place by two or more rivets 34 in rivet holes. The right wall 30 has a variable position cavity 35 and shows a line of an outward score 38′ and another line for an inward score 39,39′. A folded wing 40 supports the partially removed wall mount piece 42. Between right wall 30 and bottom fold 36 there is an inward score 39″, similarly along the left side, between the front wall 22 and the left wall 24 there is an inward score 39 which proceeds as far as the start of the mike slot 25; also between the left wall 24 and the bottom fold 36 there is an inward score 39′″, and between the front wall 22 and the bottom wall 26 there is an inward score 39″″. To provide a support for a wall mount piece there are provided two wings 40, 40′ connected to the right hand wall 30 and to the left wall 24 by scored junctions. In FIG. 1 the scored junctions are outward scores 38′ and 38 which indicate a position for an overlapping wall mount piece comprising the width of the front wall plus the sum of the widths of the wings 40′ and 40. Such arrangement might be suitable for a wall mounted case and not for a portable case. A wall mount piece is identified 42.

FIGS. 2A, 2B, 2C, 2D show a wall thickness 28 with in FIG. 2A a minimum removal 48, which serves to connect an outward link 44, which becomes in FIG. 2B an external arc 44′ and leaving an outward score 38. FIG. 2C shows a maximum removal 50 from a wall leading to an inward link 46, which becomes in FIG. 2D an enclosing arc 46′ circling an inward score 39. In short one sees the opening of the outward link 44, which is straight in FIG. 2A and becomes a curved external arc 44′ in FIG. 2B. One sees an inward link 46, which is also straight in FIG. 2C and is curved along an enclosing arc 46′ in FIG. 2D. One also sees in FIG. 2A a scoring of a plastic depth appearing as a minimum removal 48 next to a maximum removal in FIG. 2C, in a second area of scoring, the withdrawal permitting to close an inward link 46′ in FIG. 2D to surround the inward score 39. In FIG. 2E an alternative is shown to the inward link 46 with reinforcements 56.

FIG. 3 shows a complete arrangement of a portable case with all its wings in the process of being folded, with a fullback flap being present and adapted to cover the wings 40 and 40′. An inward score 39′ reaches to about 5 mm from the mouth of the case showing an internal filling 54′ of original matter; it is also the inward score 39 which reaches approximately 5 mm from the mike slot 25 showing an internal filling 54 of original matter. This area of original matter approximately doubles the strength in tear resistance. Actually a folded wing 40 must be turned beneath a fullback flap 43 that could be longer than the front wall 22. An original filling of more than 5 mm is not recommended and does not allow a fold as precise, defined and controlled to 90° degrees. One may add other matter of origin, for example at each distance of 35 mm or 45 mm. In addition there are rivets and holes 34 therefor.

FIG. 4 shows the embodiment of FIG. 3 laid flat before the components are assembled and inter-related. One notices the references 54′, 52′, 39′ corresponding to the right parts identified as 54,52,39 to the left. There is a fullback flap 43 not exceeding the width of the front wall 22. The wings 40 may exceed in length the side walls 24, 30 left and right. Holes for rivets 34, 34′ are positioned to be stacked when bottom folds 36, 36′ are rotated 90° degrees to cover the bottom wall 26. One sees flap holes 64 which are positioned to match wing holes 66.

FIG. 5 show as FIG. 5A a 90° bend with a thickness 28, a width 29 and an inward score 39; as FIG. 5B a minimum score 58 depth removal which leaves a large width 29′ of non removed original matter, and a short bend of 45°. As FIG. 5C a major score 60 which permits a thin width 29″ and a long bend of 135°.

FIG. 6 shows a top view of a case with wings 40,40′ folded and about to be covered by the fullback flap 43. Flap holes 64 are also to match wing holes 66. One sees a cavity 74 for a screen of a walkie-talkie and a keyboard cavity 76.

FIG. 7 shows a perspective of a case 20 ready to be used with at the top a tie 70 finished by a pressure button 72 to be fixed on the front wall 22 for maintaining in place a walkie-talkie inside the case. A rivet shield 68 is used to protect a walkie-talkie from scratches caused by the contact with flap rivets 65 screwed inside flap holes 64 of the fullback flap 43. The central cavity 35 and the mike slot 25 are shown.

SUMMARY OF THE INVENTION

A plastic body worn case 20 for portable electronic devices, the case comprising: a front wall 22, a back wall 42, two side walls 24 left and right 30, a bottom wall 26, a wall thickness 28, the walls being joined to form an open face parallelepiped and defining a number of junctions between the walls, at least one of the junctions including a partial removal of the thickness 28. The partial removal leaves a non-removed original matter to produce an inward link 46 which may be bent into an enclosing arc 46′ around an inward score 39 around which two walls are adjacent to and oriented 90° degrees one compared to the other. The arc length is larger than 1½ times the thickness to close two adjacent walls, a first wall in relation to a second wall, the length of an inward arc defining a maximal removal 50. The external arc 44′ has a preferred external arc length equals to ½ times the thickness 28 to close two adjacent walls, one over the other, the length of external arc 44′ is smaller and defines a minimum removal 48. The walls are made of materials to be used in combination with illuminating means such as a rather hard plastic. The side walls are folded at the inward scores 39,39′ and include folded wings 40 (see FIG. 3) from scores 39″ and 39′″ are normally rotated 180° degrees to join the left side to the right side and become a pair of inward slots and the two folded wings 40 will be met by a fullback flap 43 (see FIG. 6) in length corresponding to the length of the front wall 22. The side walls 30,24, the bottom wall 26 and the fullback flap 43 are assembled with the bottom folds 36,36′. The walls are made of plastic materials, synthetic materials, smooth to the touch with or without added materials. A rivet shield 68 is used to protect a walkie-talkie inside the case from scratches caused by the contact with flap rivets 65. The walkie-talkie may be maintained in place by the use of a tie 70 in the top of the case.
